$L^{p}$ -regularity for fourth-order Schrödinger operators with unbounded or degenerate coefficients

Federica Gregorio, Chiara Spina, Cristian Tacelli

We prove that operators of the form $A = - Δ^{2} - V (x)$ , with $∣ D V (x) ∣ \leq γ V (x)^{\frac{5}{4}} + C_{γ}$ for some $γ$ small enough and $C_{γ}$ positive constant, generate analytic semigroups…

Higher order Schrödinger operators

Federica Gregorio, Chiara Spina, Cristian Tacelli

In this paper we consider higher order Schrödinger operators $L u = Lu + V u,$ where $L$ denotes a fourth order operator and $V \geq 0$ a suitable potential. We initiate our a…
